PROBLEM TO BE SOLVED: To suppress vibration in a drive system, at the same time suppress the increase in engine revolution, and rapidly connect the engine to a motor/a generator directly to complete start. SOLUTION: A target motor/generator torque T*M/G is obtained from an engine speed NE and a throttle opening TH by map search using feedforward, and is passed through a low-pass filter for passing a lower frequency band than a drive system vibration frequency to remove a drive system vibration component. In the map, the target motor/generator torque is set to zero, at a region that is lower than the idle speed of the engine, gain is increased at a region up to a desired directly coupling speed and the speed for the motor/ generator is increased. For an engine speed that is lower than it, a torque that is equivalent to that of the engine is generated, and the engine and the motor/generator are directly coupled. |
